What is shrinkflation?
Shrinkflation is a form of hidden inflation where the size or quantity of a product decreases while its price remains the same or increases. Instead of raising the price outright, manufacturers reduce the package size — so you pay the same (or more) for less. Common examples include chocolate bars getting smaller, cereal boxes losing ounces, and ice cream tubs shrinking. This calculator exposes the true cost per unit and the hidden inflation you're actually paying.
Example: A chocolate bar that used to be 100g for $5.00 is now 80g for $5.50. The price per gram went from $0.050 to $0.069 — a 37.5% effective price increase, even though the price only went up 10%.
